Abstract

A drive unit includes a drive pulley (103), a driven pulley (105) at least one relay pulley (104) for transmitting power from the drive pulley to the driven pulley, a plurality of belts (101,102) including a first belt (101) entrained around the drive pulley and the relay pulley, and a second belt (102) entrained around the relay pulley and the driven pulley, a first tension application device (108), and a second tension application device (109). The first tension application device contacts the first belt to provide tension thereto. The second tension application device contacts the second belt to provide tension thereto. A cyclic speed variation component of the first belt in one rotation period transmitted to the driven pulley via the relay pulley and a speed variation component of the second belt in one rotation period transmitted to the driven pulley counteract each other.
